The childhood sweethearts will welcome the new bundle of joy next month, the Irish Independent reports.

Their new baby will most likely be arriving at a busy time for the Leinster player as Ireland launch their campaign to keep their RBS Six Nations title with their opening game against Wales on February 7.

The couple, both 30 years old, wed at Adare Manor in Co Limerick in July 2013 - a decade after they first met as teenagers.

The pair's new arrival will be a brother or sister for their 19-month-old son Luca.
